Answer Happy

At least one of the answers above is NOT correct. Let f(x) = 4vvel for x > 0. Fill in the values or intervals below. If there is nothing applicable for a given category enter NONE . For o use infinity. For -00, use -infinity. To indicate a union of intervals, use U. interval(s) on which f is increasing (0, 1/2) interval(s) on which f is decreasing (-infinity, O) U (1/2, infinity) point(s) at which f achieves a local maximum 1/2 point(s) at which f achieves a local minimum none interval(s) on which f is concave upward (1/2 + sqrt2/2, infinity) interval(s) on which f is concave downward (0, (1+sqrt2)/2) Use your results, as recorded above, to sketch the graph of f. Check your result by making a plot (not submitted) .
